Fedora Core 6 (as with every other Linux distro) is a great OS for someone who has the skills, time, and inclination to play sysadmin. For those of us who do not have the skills, the time, or the inclination to do so, Linux is still a very poor choice, and we're stuck, for better or worse, with either OS X or Windows.
Why? Linux is no more difficult than Windows or Apple. It's different, sure. It requires the user to learn different ways of doing things, but it's as easy, if not easier, to do everything you need to do as Windows.
For me, Linux is MUCH better...
Besides not having to pay for the operating system, I don't have to pay for the "office suite", or put up with a downgraded "works" office.
I don't have the time to put up with Microsoft frustration, and to work on filling up all their security holes.
I've been running Linux without ANY virus or spyware protection for two years, only a hardware firewall/router. NO problems at all.
It is worth it to convert to Linux... which is getting better and better.
I suggest people try "Knoppix" ... an operating system that boots up from CD (or DVD) to see if Linux might suit them. That does not change their computer at all! Good for a "test drive". Then that they obtain and install one of the several excellent flavors: Fedora, Linspire (apparently good for laptops right now), Mandriva, etc. in a "dual-boot" environment, so they can switch between MS and their Linux, as I have. It has now been over a year since I've logged into the MS operating systems on any of my computers.
